Title: Patty machine
IPC: A23L13/00
Filed: 1976-07-01
Abstract: 1508543 Moulding meat patties HOBART CORP 1 July 1976 [2 July 1975] 27550/76 Heading B5A A meat patty making device comprises a hopper 12 having a charging chamber 14 at one end. Material in the hopper is urged by a paddle assembly 24 on to a pair of intermeshing self-cleaning conveyer screws 26, 27 which convey the material to a pair of intermeshing compressor screws 28, 29 located in the charging chamber. A mould plate 20 having a cavity 18 is reciprocable to and from a position above the outlet 22 of the charging chamber to receive material from it. The mould plate is slidable between lower and upper plates 118, 120 which project back into the hopper above the entrance to the charging chamber to help guide material into the chamber. A plate 128 is located above the upper plate to define a channel with it, the channel being in communication with the mould cavity through a perforated section of the upper plate. The channel serves to allow escape of trapped gases and facilitates recirculation of excess material to the hopper. The conveyer and compressor screws are carried by shafts 30, 31 driven by drive shafts 34, 35, the screws 27, 28 and 29 being positively keyed to the shafts whilst the screw 26 is freely rotatably mounted upon shaft 30. The drive shafts are driven through suitable gearing and chains (see Fig. 10) by reciprocating plates driven from a cranked motor. The drive arrangement includes a spring biasing mechanism of varying strength which, when the outlet of the charging chamber is closed by the mould plate, elongates to accommodate movement of the plates thereby stopping rotation of the screws. Thus rotation of the screws is effected only during mould filling with a consequent reduction in working of the material. The compressor screws may also be self-cleaning, the outer edges of the flights of the screws being in wiping contact with the faces of the flights.

Patent GB-685843-A (GB)
Title: Improved cellulosic product
IPC: D01F2/08
Filed: 1949-11-01
Abstract: A cellulosic product suitable for conversion into rayon consists of cotton, or alkali cellulose formed from cotton, in which is incorporated 0.01-0.2 per cent by weight, based on the bone dry weight of the cotton, of a polyalkylene oxide polymerization compound selected from the group comprising a polyalkylene oxide, a mixed ether having attached to the ether oxygen a polyalkylene oxide radical and a hydrocarbon radical containing more than 7 carbon atoms, and a mixed thioether having attached to the sulphur atom a polyalkylene oxide radical and a hydrocarbon radical containing more than 7 carbon atoms, this polymerization compound being dispersible in water and stable in a solution of alkali metal hydroxide.  The hydrocarbon radical of more than 7 carbon atoms may be aliphatic, cycloaliphatic, or aromatic-aliphatic.  The polyalkylene oxide radical may contain 5-20 alkenoxy residues.  Saturated or unsaturated aliphatic hydrocarbon radicals may be present.  Polyethylene and polypropylene oxides may be used, e.g. polyethylene oxide which has a freezing point of at least 34 DEG  C., or polypropylene oxide having a specific viscosity of 0.065-0.138 measured at 18 DEG  C. in a benzene solution containing 4 per cent by weight of the compound.  A mixed ether containing a polyethylene oxide radical and a cycloaliphatic hydrocarbon radical derived from abietic acid may be used, e.g. the hydrocarbon radical may be dihydro-, dehydro-, or tetrahydro-abietyl.  When the hydrocarbon radical is aliphatic it may be lauryl, stearyl, or oleyl.  If desired, a mixture of fatty alcohols obtained by catalytic reduction by hydrogen of vegetable or animal oils may be used in the preparation of mixed ethers containing polyethylene oxide radicals and aliphatic hydrocarbon radicals.  A solution or dispersion of the polyalkylene oxide compound may be applied to loose cotton fibres or to felted cotton sheets.  The addition of the polyalkylene oxide compound in the cotton leads to the production of spinning solutions of high degree of uniformity, and in the case of spinning solutions containing delustring or other pigments it facilitates the dispersion of such pigments.  Its ultimate presence during filament-formation inhibits clogging of the extrusion orifices.  The process is particularly applicable to the production of filaments by the viscose process.  If desired, instead of adding the polyalkylene oxide compound to the cotton, it may be added at a stage prior to completion of the shredding of the alkali-cellulose.  Also if desired, the polyalkylene oxide compound may be added together with a small proportion of a cation-active amino compound of a kind described in Specification 685,842. Reference is also made to the use of the treated cotton in the production of other cellulosic products.  Specifications 488,620, 541,099, 557,218, 582,310, 601,783 and 634,868 also are referred to.

In a wrapping machine, the leading edge 2a of a collapsed tubular foil 2 is gripped by means carried by opposed pairs of belts 19, 20 and which open and pull the foil 2 over a stack of objects 7 on a conveyer 6, the foil then being transversely sealed and severed by welding and cutting tools 35, 36. The foil is drawn from a supply 47 by a pair of rollers 8, 9, the roller 8 being coupled to a shaft 10 by an electromagnetic clutch 11, being connected to a freewheel mechanism 12 so as to be rotatable only in a direction which advances the foil 2, and being coupled to the roller 9 by interengaging toothed wheels 14, 15. The chains 19, 20 are entrained around chain wheels 21, 22 mounted on the shaft 10 and a shaft 25, the two shafts being coupled by toothed wheels 26, 27 and driven by a motor 29 having a built-in brake 30. The chains 19, 20 either carry grippers or hollow bars 4 connected to a source of suction (not shown) by flexible pipes 17 and having openings 16 for applying suction to the foil 2. In operation, the conveyer 6 carries the stack (which may be on a pallet 38) to a position between the chains 19, 20 and is then halted. The motor 29 is then actuated so that the bars 4 open the foil (due to divergence of the chains 19, 20) and pull it over the stack. During movement, one of the bars 4 closes a switch 39 to deactivate the motor 29 and actuate a pair of cylinders 41 which, through linkages 42-44, operate the welding and cutting tools 35, 36. The tools 35, 36 are then retracted and the motor 29 restarted, the clutch 11, however, not being operated so that only the bars 4 move and pull the severed foil section completely over the stack. The conveyer 6 is then started to remove the wrapped stack and, optionally, carry it to a heat shrinking device (not shown). The bars 4, when in their lowermost position, operate a switch 45 to reverse the motor 29 to carry the bars 4 back to a position adjacent the rollers 8, 9 for further operation. To introduce the foil 2 between the rollers 8, 9 the leading edge 2a of the foil is attached to a rod 48 secured to the chains 19. The motor 29 is then activated to carry the rod through the rollers 8, 9, the foil is released from the rod 48 and gripped between the welding and cutting tools 35, 36 and the motor 29 is reversed to carry the rod 28 back to a position adjacent the supply 47.
